CRANBURY, N.J., Oct. 29 /PRNewswire-FirstCall/ --
Amicus Therapeutics (NASDAQ:FOLD)
today announced financial results for the third quarter 2009.
Additionally, Amicus also today announced that it has reacquired
all global development and commercialization rights from its
partner, Shire, for its lead lysosomal
storage disease programs as a result of the parties' mutual
termination of their collaboration. The Company also announced a
workforce reduction of approximately 20 percent and provided cash
guidance into the second half of 2011.

Amicus/Shire Collaboration Mutual Termination:

Amicus and Shire have reached a mutual termination agreement
with respect to their collaboration to jointly develop Amicus'
three lead pharmacological chaperone compounds for the treatment of
lysosomal storage disorders, effective immediately. As a result of
this agreement, Amicus has regained exclusive worldwide rights to
develop and commercialize Amigal(TM)
(migalastat hydrochloride), Plicera
(TM) (afegostat tartrate) and AT2220
(1-deoxynojirimycin HCl) outside of the United
States (U.S.) and now owns worldwide rights for these programs.
Shire will pay Amicus $5.2 million in the fourth quarter as full
and final payment for any amounts that may be due to the Company
under the collaboration, and both parties will be relieved of all
other future obligations, financial or otherwise.

John F. Crowley, President and CEO of Amicus Therapeutics
stated, "Shire has been an excellent partner to work with during
the past two years. However, reacquiring the ex-U.S. commercial
rights to Amigal furthers our desire to enhance the value of that
program for our shareholders. Since Shire and Amicus mutually
concluded that Plicera will not move forward to Phase 3 development
in Gaucher disease, having global rights to Amigal was of critical
importance to Amicus."

Amicus will continue to manage global clinical operations for
Amigal Phase 3 development and expects to initiate more than thirty
investigational sites worldwide. As previously announced, the first
global Phase 3 Amigal study is a 60 patient randomized,
double-blind placebo controlled six month study intended to support
U.S. registration. The primary surrogate endpoint agreed to with
the U.S. Food and Drug Administration (FDA) is a histological
evaluation of the change in GL-3 levels in the interstitial
capillary cells of the kidney. The first patient was randomized
into this study in mid-October. The Company estimates it will
complete enrollment for this trial by the end of 2010 and expects
to have data available in mid-2011. A separate Phase 3 study for
registration in the European Union comparing Amigal with
Fabrazyme® is required by the
European Medicines Agency (EMEA). Amicus expects to provide a
further update on that proposed study for the EMEA in 2010 as the
supply constraints with Fabrazyme become clearer.

Key Strategic Priorities and Workforce Reduction:

As part of its strategic business plan, Amicus will focus its
resources in three key areas:

-- The Phase 3 development of Amigal for Fabry disease;
-- Advancement of its lead pre-clinical programs that utilize its
pharmacological chaperone technology for the treatment of diseases of
neurodegeneration. The Company has an advanced pre-clinical program
in Parkinson's disease, as well as an earlier stage pre-clinical
program in an as yet undisclosed neurodegenerative target disease; and
-- Advancement of pharmacological chaperones used in combination with
enzyme replacement therapies (ERT) for the treatment of lysosomal
storage diseases.

"By focusing our resources on these three value creating centers
within Amicus, we will balance the execution of our global late
stage clinical program in Fabry disease with continued significant
investment with the chaperone platform in diseases of
neurodegeneration, which continue to yield very exciting near-term
and long-term potential value for the Company. The chaperone-ERT
combination approach is also one of potentially significant value
for Amicus shareholders as a further extension of our technology,"
said John F. Crowley.

The Company also announced today a work-force reduction of
approximately 20 percent, or 26 employees, as a part of a corporate
restructuring, with reductions occurring across all levels and
organizations within the Company. In addition, Amicus is
terminating its relationship with approximately 17 contractors
currently working at the Company. Amicus is taking this step to
reduce costs and to align its resources with its key strategic
priorities. The Company estimates that it will record charges of
approximately $0.9 million during the fourth quarter of 2009 for
employment termination costs payable in cash in connection with the
workforce reduction.

"After extensive review of our business plan, we have made some
very difficult decisions to restructure our workforce to best
enable us to align the Company around the three key strategic
priorities for Amicus going forward," said John F. Crowley.
"Specifically, we expect that these changes will enable our current
cash to last into the second half of 2011. It is exceptionally
difficult to implement these employee changes as so many remarkably
dedicated and talented persons, including Jim Dentzer, our Chief
Financial Officer, will be leaving Amicus. All of them have
contributed significantly to the Company, and I cannot thank them
enough for all of their tireless efforts, passion and
contributions."

"We are highly confident that with this restructuring and
strategic repositioning, we are well poised to maximize shareholder
value while ensuring that we deliver on our mission to provide
innovative and high quality therapies to people afflicted with
these diseases. We remain fully committed to the success of
Amicus," concluded John F. Crowley.

Financial Guidance:

Based on current projections of net operating expense, the
Company reiterates its expectation to end 2009 with approximately
$70-$80 million in cash, cash equivalents and marketable
securities. Additionally, the Company expects that its current
cash, cash equivalents and marketable securities together with the
fourth quarter $5.2 million payment from Shire will be sufficient
to fund operations and capital expenditure requirements into the
second half of 2011.

Third Quarter 2009 Results Summary

On a reported basis calculated in accordance with U.S. Generally
Accepted Accounting Principles (GAAP), Amicus announced a net loss
attributable to common stockholders of $0.59 per share ($0.51 per
share on a non-GAAP basis) for the three months ended September 30,
2009. As of September 30, 2009, cash, cash equivalents and
marketable securities totaled $89.3 million.

Clinical Program Updates
Amigal(TM) (migalastat hydrochloride) for the treatment of Fabry disease

In the second quarter of 2009, Amicus announced that the Company
reached agreement with the FDA on the key protocol design elements
of its pivotal trial, including the use of the surrogate primary
endpoint of the change in the amount of kidney interstitial
capillary GL-3, the substrate that accumulates in the cells of
Fabry patients. In addition, the FDA is in agreement that the
Company is eligible to seek Accelerated Approval for Amigal
according to Subpart H regulations. Amicus began submitting the
Phase 3 protocol to investigational sites worldwide in June 2009
and patient enrollment and dosing are now underway.

Furthermore, Amicus previously reported that it completed a
series of discussions with the EMEA regarding the clinical study
required for Amigal registration in Europe. The Company will
provide an update on the timing of the initiation of this study in
2010.

Plicera(TM) (afegostat tartrate) for the treatment of Gaucher
Disease

The Company previously reported preliminary results from its
Phase 2 randomized, open-label study to assess the safety,
tolerability and preliminary efficacy of its investigational drug,
Plicera, in treatment-naive adult patients with type 1 Gaucher
disease. Two dose regimens of Plicera (225 mg three days on/four
days off and seven days on/seven days off) were studied during this
six month trial. While all patients enrolled experienced an
increase in the level of the target enzyme (GCase) as measured in
white blood cells, clinically meaningful improvements in key
measures of disease were observed in just one of the eighteen
patients who completed the study. The preliminary results suggest
that treatment with Plicera was generally well tolerated, with no
serious adverse events (SAEs) reported. Nineteen subjects were
enrolled and 18 subjects completed the study. One subject
discontinued treatment because of an adverse event
(conjunctivitis-related symptoms).

The Company plans to further analyze and evaluate the results of
this Phase 2 study. However, Amicus no longer plans to advance
Plicera into Phase 3 development.

AT2220 (1-deoxynojirimycin HCl) for the treatment of Pompe
Disease

Late in the third quarter, the Company announced its plans to
initiate a Phase 1 study of AT2220 (1-deoxynojirimycin HCl), its
investigational drug in development for the treatment of Pompe
Disease. The primary objective of this study is to evaluate the
pharmacokinetics of AT2220 in muscle tissue in healthy adult
subjects. The FDA agreed to Amicus' proposal for the Phase 1 study
and subsequently converted the clinical hold of AT2220 to a partial
hold to allow the conduct of this study.

This open label, single dose Phase 1 study was initiated in
early October and the Company expects to announce results from the
trial in the first half of 2010.

Additionally, Amicus continues to be encouraged by the results
of preclinical studies designed to evaluate the use of AT2220 in
combination with enzyme replacement therapy (ERT). The Company
expects to report additional data from these studies at scientific
conferences in 2010.

Preclinical Chaperone Programs

Amicus continues to invest in research to assess the potential
for applying its versatile chaperone technology platform to the
treatment of a broad range of human genetic diseases. As part of
this effort, Amicus continues to conduct preclinical studies in
Parkinson's disease and is investing in new research aimed at
evaluating disease targets for other neurodegenerative and genetic
disorders.

Additional Financial Results & Notes

On a reported basis, the net loss attributable to common
stockholders for the three months ended September 30, 2009, was
$13.4 million as compared to $8.2 million for the same period in
2008. On a non-GAAP basis, the net loss for the three months ended
September 30, 2009, was $11.5 million as compared to $6.6 million
in the same period in 2008.

Amicus recorded revenue during the third quarter of 2009
representing two different revenue streams from the Shire
collaboration agreement. Upon signing the collaboration agreement,
Amicus received an upfront payment of $50 million that had been
recognized as revenue on a straight-line basis over 18 years from
the date of the agreement. In the third quarter of 2009, Amicus
recognized $0.7 million of the Shire upfront payment and $4.2
million of research revenue on reimbursed research and development
costs.

The differences between U.S. GAAP and non U.S. GAAP financial
results are itemized in Tables 2 and 3 and are primarily due to
pre-tax stock compensation expense.

Use of Non-GAAP Financial Measures

Amicus' "non-GAAP net loss" and "non-GAAP diluted net loss per
common share" financial measures are defined as reported, or GAAP,
net loss and diluted net loss per common share excluding certain
items further discussed below. Amicus' management uses these
non-GAAP financial measures to establish financial goals and to
gain an understanding of the comparative financial performance of
Amicus from year to year and quarter to quarter. Accordingly,
Amicus believes investors' understanding of Amicus' financial
performance is enhanced as a result of disclosing these non-GAAP
financial measures. Non-GAAP net loss and diluted net loss per
common share should not be viewed in isolation or as a substitute
for reported, or GAAP net loss and diluted net loss per common
share.

(1) Stock option expense -- Non-GAAP net loss and diluted net
loss per common share exclude the impact of the stock option
expense recorded in accordance with SFAS No. 123R. Amicus believes
that excluding the impact of expensing stock options better
reflects the recurring economic characteristics of its
business.
